Last modified

CVE-2011-3210 is a vulnerability of currently unknown severity. The ephemeral ECDH ciphersuite functionality in OpenSSL 0.9.8 through 0.9.8r and 1.0.x before 1.0.0e does not ensure thread safety during processing of handshake messages from clients, which allows remote attackers to cause a denial of service (daemon crash) via out-of-order messages that violate the TLS protocol.. EPSS estimates a 4.56% chance of exploitation in the next 30 days.
